A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station. In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones. The first hand-held mobile phone was demonstrated by John F. Mitchell and Dr Martin Cooper of Motorola in 1973, using a handset weighing around 2.2 pounds (1 kg). In 1983, theDynaTAC 8000x was the first to be commercially available. From 1990 to 2011, worldwide mobile phone subscriptions grew from 12.4 million to over 6 billion, penetrating about 87% of the global population and reaching the bottom of the economic pyramid

History of mobile phonesInventor Charles E. Alden claimed, in the 29 April 1906 issue of the New York World, to have invented a device called the “vest pocket telephone" although Alden never had the chance to produce this device in large quantities.[9][10][11] The first mobile telephone calls were made from cars in 1946. Bell System's Mobile Telephone Service was made on 17 June in St. Louis, Missouri, followed by Illinois Bell Telephone Company's car radiotelephone service in Chicago on 2 October. [12] The MTA phones were composed of vacuum tubes and relays, and weighed over 80 pounds (36 kg).[13][14] There were initially only 3 channels for all the users in the metropolitan area, increasing later to 32 channels across 3 bands. This service continued into the 1980s in large portions of North America. Due to the small number of radio frequencies available, the service quickly reached capacity. In 1956 the world’s first partly automatic car phone system, Mobile System A (MTA) was introduced inSweden. John F. Mitchell, Motorola's chief of portable communication products in 1973, played a key role in advancing the development of handheld mobile telephone equipment. Mitchell successfully pushed Motorola to develop wireless communication products that would be small enough to use anywhere and participated in the design of the cellular phone.[15][16] Martin Cooper, a Motorolaresearcher and executive, was the key researcher on Mitchell's team that developed the first hand-held mobile telephone for use on a cellular network.[17] Using a somewhat heavy portable handset, Cooper made the first call on a handheld mobile phone on 3 April 1973 to his rival, Dr. Joel S. Engel of Bell Labs.[18][19] As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973, there weren't cordless telephones or cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter - probably one of the more dangerous things I have ever done in my life. —Martin Cooper, [20]

The new invention sold for $3,995 and weighed two pounds, leading to a nickname "the brick". The world's first commercial automated cellular network was launched in Japan by NTT in 1979, initially in the metropolitan area of Tokyo. In 1981, this was followed by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway and Sweden.[21] Several countries then followed in the early-to-mid 1980s including the UK, Mexico and Canada. On 6 March 1983, the DynaTAc mobile phone launched on the first US 1G network by Ameritech. It cost $100m to develop, and took over a decade to hit the...

MobilePhone Security
This fact sheet has been developed for the Consumer Education Program by the Communications Commission of Kenya. It was compiled by studying material from various authoritative sources and adopting what is universally acceptable and relevant to the Kenyan situation. The fact sheet is intended to enable Consumers have a good understanding of the issues discussed and hence empower them when making decisions regarding ICT products and services. Introduction One of the biggest threats that a mobilephone user faces today is loss or theft of the phone. Not only is the mobile valued as a physical device, the phone may contain personal and financial data stored in the handset or in the phones subscriber identity module (SIM card). While a stolen SIM can be barred by a mobile network once the theft has been reported it is a bit harder to bar the handset from being used with different SIM card. Unless the user had protected his personal information with a PIN prior to the theft or loss of the phone, this data can be accessed by unauthorised persons. Mobilephone users normally store a wide range of information on their phones. This information can either be stored in the phone’s internal or external memory (depending on the make and model of the phone)...

...The cellular phone industry has evolved over a period of 20 years, from first generation to third generation mobiles. The inventions by mobile industry incorporate:First Generation (1G) -The first generation mobilephone refers to the mobilephones that were developed in the 1980s. Second Generation (2G) -GSM, CDMA and TDMA are the different protocols that brought the mobilephone into the second generation stage. The 2G was introduced to the market basically in the early 1990s. Second And a Half Generation (2.5G) -Still under the same network protocol, but provided services such as WAP and GPRS enabling mobilephones to access on certain websites. Coloured screen with camera featured mobilephones were also introduced in this stage. Third Generation (3G) -A whole new network protocol launched in the twenty-first century. It is either under IMT-2000, UMTS or W-CDMA standards. The 3G protocol enables high speed connection (speed similar to broadband connection) to access through internet and also video calls.
Handsets have become a necessity from a luxury. The mobile industry has influenced the lives of millions of people worldwide. From being only a voice communication device; the mobile handset has gradually become part of user’s personality. The cellular...

Mobile Web Applications, CDMA, and GSM
Mobile Web Applications are a development stemming from use of the Mobile Web. Stallings and Case explain the Mobile Web as:
...another name for the collection of Web sites and wireless portals that have been designed for access from mobile browsers. Some automatically create “mobile” versions of their Web pages for users who use mobile devices to access the Web site. (Stallings & Case, 2012, p 495)
Today's modern smart phones use a variety of applications in order to better the end user's experience and allow them to perform a variety of tasks. According to Lionbridge, “Mobile applications come in two distinct formats: native apps and web apps. Due to differences in their underlying technology, each approach has inherent advantages and drawbacks” (Lionbridge, N.D., p 2). A mobile web application is typically formatted for smart phones or tablets, is accessed thorough the phone's web browser, is intended to be platform or device independent, and typically uses three core technologies: HTML, CSS, and JavaScript. A native mobile application is normally built for specific phones or...

...a situation where the mobilephone did not exist,upto to today when almost everyone has one and it has become a necessity
This essay will discuss the Mobilephone and look at its origins and analyse how it has evolved over time to become a necessity in the present day.
A MobilePhone or cellular phone is a device that is used to make and receive telephone calls over a radio link over a wide geographical area.It does this by connecting to a cellular network provided by a mobilePhone operator like MTN,CellZ and Airtel in Zambia.A mobilephone can also connect to a public telephone network i.e Land line.In Zambia,Zamtel provides Land line telephone services.
In the early days,communication of speech by radio link was mainly used by the Military using hand and held radio transceivers.These were also used for transmiting radio waves from land to the ship on the seas.Early communication devices of this nature were bulky and required colossal amount of energy.They also supported only a few simultaneous conversations.Modern day Mobilephone networks are able to accommodate multiple conversations and can also be used for data communication.
For many of us, it's hard to imagine a time before cell phones. Until very recently, most of the people who carried mobile...

...Mobilephone industry started to emerge in the Philippines during the 1990’s. Before the 90s, telecommunications was a business for only fixed line operators which majority is owned by PLDT. Majority of mobile communications then rely on unsecured frequency-band walkie talkies.
A little later, mobilephones the size of a one-liter bottle were introduced utilizing GSM technology. Further forward, the size of these devices have shrunk into the newer models and beepers have been introduced. With a combination of the functionalities of these two independent devices, the introduction of short messaging service in the GSM technology has popularized the use of mobilephones.
Filipinos are innately social, and non-confrontational in nature, and thus, communication pays a vital part in day to day life. And, with an inexpensive access to SIM cards and SMS service, mobilephones have been a fad.
According to a survey recently (2012) conducted by global research agency Synovate, one out of every 4 (Filipino) surveyed, said they can't live without a mobilephone. The number of mobile subscribers in the Philippines is expected to reach 117 million by end-2016 and will have a 114% penetration rate by end-2016, according to a report by Business Monitor International (BMI).
In the Philippines, Nokia, Samsung, Sony...
